Panty-RAID1 -4- CentOS

So I am working on an older system today, CentOS 4.4 – 2.6.18-93.cc4 to be quite specific and I needed to add a RAID1 mirror to the existing filesystem because for whatever reason, when this server was built, it was all built under / ?  Well just goes to show you, don’t do that, especially if you are locally storing IMAP emails!  Anyway, this should be a good tutorial on how to do this should you encounter a similar situation.

I made a remote backup of the /home and /var fs just in case… 🙂  incidentally, those are what we are working on here.

First, (LOL) shutdown the system and install the new hard disks…

If you are super-duper lucky (like me) upon restart, your hardware will see the new disks just installed, validate that this is also true for you…

dmesg|grep hd (grep for whatever your /dev designation is for hd's)
ide0: BM-DMA at 0xf800-0xf807, BIOS settings: hda:DMA, hdb:pio
ide1: BM-DMA at 0xf808-0xf80f, BIOS settings: hdc:DMA, hdd:DMA
hda: WDC WD800BB-00JHC0, ATA DISK drive
hdc: WDC WD3200AAJB-00J3A0, ATA DISK drive <-- New drive
hdd: WDC WD3200AAJB-00J3A0, ATA DISK drive <-- New drive

Cool I see my 2 new 320GB disks… 🙂

On to fdisk… I am only going to show the one disk as they are both identical for my task and the process is the same no matter what you are doing with your disks.

fdisk /dev/hdc
The number of cylinders for this disk is set to 38913.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
Command (m for help): p
Disk /dev/hdc: 320.0 GB, 320072933376 bytes
255 heads, 63 sectors/track, 38913 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot      Start   End     Blocks      Id  System
/dev/hdc1        1       19456   156280288+  fd  Linux raid autodetect
/dev/hdc2        19457   38913   156288352+  fd  Linux raid autodetect

So this is the finished, written fdisk-ing.  I am going to assume you can figure this part out on your own and say that from the menu, select “n” for “add a new partition” make it primary, and for my task I needed 2 equal sized partitions so I did that as illustrated above giving me 2 147GB partitions to use:

Device Boot      Start   End     Blocks      Id  System
/dev/hdc1        1       19456   156280288+  fd  Linux raid autodetect
/dev/hdc2        19457   38913   156288352+  fd  Linux raid autodetect
Device Boot      Start   End     Blocks      Id  System
/dev/hdd1        1       19456   156280288+  fd  Linux raid autodetect
/dev/hdd2        19457   38913   156288352+  fd  Linux raid autodetect

A word of advice here… see the ID? make sure to set it to “fd” or your array will not come back when you reboot… The fd is the linux auto-detect RAID identifier…

Now create the arrays:

mdadm --create /dev/md0 --chunk=64 --level=raid1 --raid-devices=2
/dev/hdc1 /dev/hdd1
mdadm --create /dev/md1 --chunk=64 --level=raid1 --raid-devices=2
/dev/hdc2 /dev/hdd2

Make the file systems:

mkfs.ext3 /dev/md0
mkfs.ext3 /dev/md1

Check the array(s);

cat /proc/mdstat
 Personalities : [raid1]
 md1 : active raid1 hdd2[1] hdc2[0]
 156288256 blocks [2/2] [UU]
md0 : active raid1 hdd1[1] hdc1[0]
 156280192 blocks [2/2] [UU]
 [=====>...............]  resync = 26.7% (41758400/156280192) finish=56.8min

*NOTE – the resync process in-process may take a bit of time to complete…

Make the temp mount points:

mkdir home1 var1

Now this part is purely subjective, but I like to do it this way, you can do it however you like.

Edit /etc/fstab adding your new filesystems:

LABEL=/                 /                ext3    defaults        1 1
LABEL=/boot             /boot            ext3    defaults        1 2
/dev/md0                /var             ext3    defaults        1 1
/dev/md1                /home            ext3    defaults        1 1
none                    /dev/pts         devpts  gid=5,mode=620  0 0
none                    /dev/shm         tmpfs   defaults        0 0
none                    /proc            proc    defaults        0 0
none                    /sys             sysfs   defaults        0 0
LABEL=SWAP-hda2         swap             swap    defaults        0 0

Now mount them:

mount -a

df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/hda3              72G   60G  8.4G  88% /
/dev/hda1             194M   12M  173M   7% /boot
/dev/md0              147G   31G  109G  22% /var1
/dev/md1              147G   11G  130G   8% /home
none                  982M     0  982M   0% /dev/shm

There is also another file to ensure that you have, /etc/mdadm.conf, and it should look like this:

cat /etc/mdadm.conf
ARRAY /dev/md1 level=raid1 num-devices=2 UUID=75a8bc67:d6c5a49f:9f889373:47899702
ARRAY /dev/md0 level=raid1 num-devices=2 UUID=f4aa0764:0cb7aa5f:6d175968:58c838dd

There is a neat trick to get this info…

mdadm --examine --scan >> /etc/mdadm.conf

Done !

I would suggest rebooting to ensure that everything comes back as expected…

SUN-Jail – Solaris 10 convicted ! Part II Dammit… I forgot to lock the door !

OK… so hopefully you already went through Part I, but if not, this may not make much sense as I am not going to re-visit anything here.  This is for the mod_tls setup for ftps or ftpes if you are using filezilla… I was not familiar with the ftpes connection state, but now I am and so are you… I was using fireFTP and everything was working fine, but in the interest of testing more than what I use, I found this new tidbit of information 🙂

So lets first tweak the proftpd.conf file, add this to the bottom of the file:

<IfModule mod_tls.c>
TLSEngine                  on
TLSLog                     /var/log/proftpd/tls.log
TLSProtocol                SSLv23
TLSOptions                 NoCertRequest
TLSRSACertificateFile      /etc/proftpd/ssl/proftpd.cert.pem
TLSRSACertificateKeyFile   /etc/proftpd/ssl/proftpd.key.pem
TLSVerifyClient            off
TLSRequired                off
Take note of the files referenced here.  Go ahead and create the log dir, def do this as you will need it if anything is not working… and then we can move on to making the key/cert.  Keep in mind that I am using webmin for the proftpd control and it allows you to apply changes following a save eliminating the need for a manual restart of proftpd 🙂

Make this dir, please make this or the key/cert command will whine like a bitty baby…

mkdir -p /etc/proftpd/ssl

Then make the key/cert:

openssl req -new -x509 -days 365 -nodes -out /etc/proftp /ssl/proftpd.cert.pem -keyout /etc/proftpd/ssl/proftpd.key.pem

Make sure to answer all the posed questions:

Country Name (2 letter code) [AU]: <-- Enter your Country Name (e.g., "DE").
State or Province Name (full name) [Some-State]: <-- Enter your State or Province Name.
Locality Name (eg, city) []: <-- Enter  your City.
Organization Name (eg, company) [Internet Widgits Pty Ltd]: <-- Enter your Organization Name (e.g., the name  of your company).
Organizational Unit Name (eg, section) []: <-- Enter your Organizational Unit Name (e.g. "IT  Department").
Common Name (eg, YOUR name) []: <--  Enter the Fully Qualified Domain Name of the system (e.g.  "").
Email Address []: <-- Enter your Email  Address.

And again now we are done.  Not too bad… right?  I set up a few test users to allow me to tail the log file and watch as they login to make sure I can see what is expected as well as what isn’t…

SUN-Jail – Solaris 10 convicted ! Part I

OK… so a while back I did something about jails for FTP… Odd that I don’t even remember what it was for let-alone being to lazy to go back and look to make proper reference here.. but anyway, I have a successful and simple approach to doing this on Solaris 10 and seeing that I get ALOT of hits for my Solaris posts, this may in fact be another good destination. I went back to my tried and true buddy, webmin for this, with as little effort as possible.  I decided to use the ProFTPd module that comes (icon anyway) included with webmin for Solaris (which by the by, is also a default package on Sol 10) and packages from the sunfreeware site.  So lets get started with the required packages and some basic system tweaks you may or may not need:

I started out making a repo dir under /export/home as it is a large one on these systems:

mkdir /export/home/sunfreeware

cd /export/home/sunfreeware

For whatever reason, the default $PATH for Solaris 10 is as bare as it comes, leaving out lots of cool, already installed tools, like wget for example. I created a .profile and added this PATH:


This covers everything I found useful without absolutes (and without actually knowing where the f’ it is !!!)…

Here is a listing of what I needed: (You may or may not need all of these)


So lets quickly grab these…

cd /export/home/sunfreeware (in case you were not there already 🙂 )

for i in gcc-3.4.6-sol10-x86-local.gz make-3.81-sol10-x86-local.gz   openssl-1.0.0-sol10-x86-local.gz proftpd-1.3.2-sol10-x86-local.gz rssh-2.3.2-sol10-x86-local.gz; do wget$i; done

Then gunzip them:

for i in `ls`; do gunzip $i; done

The pkgadd them:

for i in `ls`; do pkgadd -d $i; done (You will need to answer at least the creation of the /usr/local/bin dir if it is not already there and the default ‘ALL’ question for each recursion)

Before you get yourself all in a tizzy… lets stop the defalt FTP service:

svcadm disable network/ftp

OK… now lets install webmin:

webminsetup (see how handy our PATH has been so far… 🙂 )

Answer the questions however you like… and wallah… Done 🙂

Now we need to make a few tweaks to the ProFTPd settings:

So you may have to click on this pic to see the line to which I am referring but in any event you want to uncomment this line so that ALL users are jailed to their defined home dir… and let me tell you that this is as easy as that process gets.  There is one other designation we need to make to ensure this takes place but it is in fact a radio button, so nothing overly complex there.  I also made the usual permissions changes on the user dirs to ensure the most security possible and a few other changes… well lets look at that step one by one shall we…

OK, so as you can see (from the wget up above) I grabbed rssh, a restricted shell.  Weather or not any of this is actually necessary is highly speculative, but I will at least illustrate what I did.


allowsftp <– This is all I wanted to allow

# If you want to chroot users, use this to set the directory where the root of
# the chroot jail will be located.
# if you DO NOT want to chroot users, LEAVE THIS COMMENTED OUT.
chrootpath = /export/home/chroot <– Make this whatever you are jailing your users to

You will also need to make an entry in /etc/shells (and create it if it is not there):


ftptest:x:104:100:FTP Test User:/export/home/chroot/ftptest:/usr/local/bin/rssh

# id ftptest
uid=104(ftptest) gid=100(ftptest)

drwx——   2 ftptest ftptest      512 May 20 15:17 ftptest

From the main module screen simply select the “Files and Directories” option to open the module.  I should mention that we are already in the ProFTPd module at this point so if you are not there, simply click on the “Servers” link in the top left and then select “ProFTPD Server” and you will be at this very page.  Take note of where things are in Webmin as surely you will want to go back and make lots of additional amendments to whatever else you have running on the system.

All we are looking at here is making sure that you restrict the user to their home directory. This may be kind of obvious, but make sure you START the service as well… It can be done from any module.  Up in the right corner you will see a “Start ProFTPd Service” button… click it.  I would also run a few commands from the console just to see what you have going on as well maybe you just should have some understanding outside of a graphical environment of what is really taking place here.  So lets run some simple commands shall we???

# ps -ef |grep ftp
ftptest2  4951  4430   0 10:38:45 ?           0:00 /usr/local/sbin/proftpd
nobody  4430     1   0 10:20:35 ?           0:00 /usr/local/sbin/proftpd
root  5193  4197   0 12:43:10 pts/2       0:00 grep ftp

Make sure you don’t see anything other than the proftpd service running… (remember we stopped the default ftp service earlier right??? )

# /usr/local/sbin/proftpd -vv
– mod_tls/2.2.1: compiled using OpenSSL version ‘OpenSSL 0.9.8k 25 Mar 2009’ headers, but linked to OpenSSL version ‘OpenSSL 0.9.8n 24 Mar 2010’ library
ProFTPD Version: 1.3.2 (stable)
Scoreboard Version: 01040002
Built: Wed May 13 16:36:46 EDT 2009

Loaded modules:

And that’s it 🙂 Go and test it to ensure you have achieved the expected results:

This is exactly what I was expecting. Make sure you cannot move out of this dir and you are all set… 🙂

So this is all fine and dandy, but who wants to use regular FTP?  I would hope no one in a business environment anyway… Part II deals with using the mod_tls module packaged with proftpd.  For whatever reason, it was actually a pretty big pain in the a$$ to get this whole thing working…

AIX-ercise in filesystem Gymnastics

So for the last few hours I have been preparing for a change window I have this weekend to get a customer ready for a migration/upgrade.  I really don’t like AIX but this one just about brought me to my knees… I know a perfect image, open wide banana boy!!!

Not sure why I am even posting this aside from the simple fact that I spent so much time on it and want to see it in all it’s splendor somewhere other than in my editor…

I’m not even going to explain this one… Looks like I thought about making this one interactive/automated but it really is a one-off… and since every AIX system I manage, someone else built (ya no consistency) there isn’t much point by way of re-usability…If you are doing some AIX disk extending, maybe this will help you, or maybe not… Maybe I will comment on my own success/failure Monday after I actually do this… although I did do a dry-run of all this on a test box I have… LOL 🙂

I am no arTist, but it works…

Hey, I like to script as much as the next guy, but I have always wondered why as a UNIX/Linux Admin/Engineer there are so many “similar” instances of issues and a plethora of examples on-line, yet very few, if any, complete (and functionally tested) interactive automated programs (if I don’t call it a program, even though it is not a “program,” it remains a script and we are stuck in a loop).  Anyway, much of what I do and I suspect what you do as well if you are reading this, kinda needs to be done pretty fast… ya know on the fly and it is quite repetitious.  So why not have a tool kit so to speak to perform these recurring tasks, instantly?  In a previous post I listed my Zimbra maildrop checker… this is in the same vein, however that was just a tool to discover information and then you have to manually execute the fix.  This one does it all for you and asks only a few questions.  I don’t know… maybe I am barking up the wrong tree here.  I guess in reality what I am trying to make is a command line Webmin?  Even though I love Webmin, I still cannot give up the command line…. LOL.  Hmmm… maybe I should just learn Perl and make these things FOR Webmin… Below is a little ditty to reduce an LV then extend another LV with the realized free PE.

# Filesystem resize:
# for some filesystem to be reduced to grow another filesystem(s)
df -h
echo “Enter the filesystem you are unmounting, including the ‘/'”
read unmountfs
fuser -mv $unmountfs # <– or whatever fs you are unmounting
for i in `fuser -mv $unmountfs|grep -v PID`; do kill -9 $i; done
read -p “If this looks OK, Press any key to continue.”
lvol=`df -H $unmountfs|grep -v $unmountfs|grep -v File`
umount $unmountfs
sleep 1
echo “Using the information above, answer the following questions…”
sleep 2
e2fsck -f $lvol
echo “Enter the NEW reduced size of the lv; i.e. 2G, 200M, etc…”
read newsize
resize2fs $lvol $newsize
lvreduce -L $newsize $lvol
mount $unmountfs
# Now lets extend the other filesystem(s)
echo “Check your FREE PE now…”
vgdisplay |grep “Free  PE / Size”
df -h
freepe=`vgdisplay |grep “Free  PE / Size”`
echo “Enter the name of the full LV name you wish to extend”
read fullv
echo “Enter no more than `vgdisplay |grep “Free  PE / Size”|awk ‘{print $5}’` Physical Extents”
read PE
lvextend -l +$PE $fullv
echo “Now compare the original FREE PE to the new FREE PE”
echo $freepe
vgdisplay |grep “Free  PE / Size”
df -h

Please keep in mind that I have NOT written any logic into this one yet… so… If you f’ something up… you might be in trouble.  I guess I have taken into assumption that whomever is using this knows what I am doing and can at least make fun of my “less than Earth shattering” scripting…

I am no arTist (pronounced r-Tee-st), but it works. 🙂

Whatever Works… right?

Here are some quick -n- dirty one-liners that I happened to use today; in no particular order:

qshape incoming active deferred

for i in `ls -l |grep “07:”|awk ‘{print $9}’`; do rm -Rf $i; done

mailq | tail +2 | awk ‘BEGIN { RS = “” } /MAILER/ {print $1} ‘ | tr -d ‘*!’ | postsuper -v -d –

find /var/lib/amavis/tmp –mtime +30 -print -exec rm -f {} \; >> $logf 2> /dev/null

No explanation necessary right?
